What is natural selection? What are some examples? What were the determinative factors that propelled the human brain to evolve during our natural selection process? What kind of behaviors may have been shaped by natural selection? What are the two conditions that are necessary and sufficient for...
Can adaptations of organisms only occur through natural selection? According to Darwin, what will happen to organisms with traits that are best suited for their environment? What conditions can cause evolution to take place? What is the relationship between biological fitness and natural selection?
In general, how do inheritance, mutation, and selection impact variation in a population? What is the relationship between population genetics and natural selection? What are the two conditions that are necessary and sufficient for natural selection to bring about evolutionary c...

'Natural selection' is, it seems, an ambiguous term. It is sometimes held to denote a consequence of variation, heredity, and environment, while at other times as denoting a force that creates adaptations. I argue that the latter, the force interpretation, is a redundant notion of natural ...
